I ran a 'cat /proc/cpuinfo' on a node I'm using and obtained the following:
processor : 13
vendor_id : GenuineIntel
cpu family : 6
model : 62
model name : Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
stepping : 4
cpu MHz : 1200.000
cache size : 25600 KB
physical id : 1
siblings : 10
core id : 3
cpu cores : 10
apicid : 38
initial apicid : 38
fpu : yes
fpu_exception : yes
cpuid level : 13
wp : yes
address sizes : 46 bits physical, 48 bits
Why is "cpu MHz :1200", while the model name says it runs at 2.8Ghz?
2You have frequency scaling enabled. Many modern CPUs (at least of the x86/x86_64 families) can run at lower speeds to reduce power consumption when they're not busy doing stuff. The speed will be increased when there is demand for it. – twalberg – 2014-02-28T20:38:08.460
Looks like a ServerFault or SuperUser question, not StackOverflow? – Peterdk – 2014-02-28T20:51:02.950
